Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 1,798,067, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
1 | 1,798,067 | |
-1 | -1,798,067 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,798,067.
Example:
1 x 1,798,067 = 1,798,067
and
-1 x -1,798,067 = 1,798,067
Notice both answers equal 1,798,067
With that explanation out of the way, let's continue. Next, we take the number 1,798,067 and divide it by 2:
1,798,067 ÷ 2 = 899,033.5
If the quotient is a whole number, then 2 and 899,033.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
1 | 1,798,067 | |
-1 | -1,798,067 |
Now, we try dividing 1,798,067 by 3:
1,798,067 ÷ 3 = 599,355.6667
If the quotient is a whole number, then 3 and 599,355.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
1 | 1,798,067 | |
-1 | -1,798,067 |
Let's try dividing by 4:
1,798,067 ÷ 4 = 449,516.75
If the quotient is a whole number, then 4 and 449,516.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
1 | 1,798,067 | |
-1 | 1,798,067 |
If you did it right, you will end up with this table:
1 | 89 | 227 | 7,921 | 20,203 | 1,798,067 |
-1 | -89 | -227 | -7,921 | -20,203 | -1,798,067 |
